Del CaldwellThis paper provides an introduction to the new ANSI/NCSL Z540.3 standard and its approach to prescribing requirements for a calibration system that controls the accuracy of the measuring and test equipment used to ensure that products and services comply with prescribed requirements. The new ANSI/NCSLI Z540.3 standard replaces Part II of the current standard, ANSI/NCSL Z540-1 (R2002). Z540.3 consists of six clauses, each of which is described: Scope; References; Terms ...

This Handbook was developed to assist those using the American National Standard for Calibration ANSI/NCSL Z540.3-2006, Requirements for the Calibration of Measuring and Test Equipment. This Handbook provides discussion and guidance for sub-clauses of the Standard, and furnishes representative examples that address key aspects of the topics discussed.

This standard has been derived from the International Organization for Standardization (ISO) U.S. Guide to the Expression of Uncertainty in Measurement to promote consistent international Methods in the expression of measurement uncertainty within U.S. standardization, calibration, laboratory accreditation, and metrology services. It is identical to the ISO Guide (corrected and reprinted, 1995) with the exception of minor editorial changes to facilitate its use in the United States.... Details

This National Standard establishs the technical requirements for the calibration of measuring and test equipment. This is done through the use of a system of functional components. Collectively, these components are used to manage and assure that the accuracy and reliability of the measuring and test equipment are in accordance with identified performance requirements. In implementing its objective, this National Standard describes the technical requirements for establishing and... Details

Perspective
Kevin Abercrombie,
Laboratory Director,
Metrology Division (AIR-4.9.2.1.1)
Naval Air Warfare Center, Aircraft DivisionIn 1998, the Navy adopted ANSI/NCSL-Z540-1 (1994) as the quality standard for all Navy and
Marine Corps calibration laboratories. With the adoption of 17025 as the standard in place of
Z540, the Navy is at a cross roads where it must decide whether to adopt the new standard or

George Jannison,
Puget Sound Naval ShipyardWhile calibration has always used standards, the processes today are required to assist in the
delivery of an ISO 17025 or ANSI Z540 compliant calibration system. Our activity developed a
management approved training plan that includes classroom sessions, written tests and
proficiency evaluation of calibrators, prior to certification.

The training plan continues to evolve as the quality program and technology add... Details

The NCSL International Glossary is a broadly scoped document, a catalogued listing terms and their definitions. The terms and definitions included are singularly focused on metrology, calibration, and all related measurements, tests, and industrial requirements. As such, the Glossary is a living document requiring periodic revision in order to stay current with the demands of global industries.

Jim SalsburyThis paper studies the impact of the conformance decision rule used in compliance assessment during the calibration process on the subsequent measurements made using the calibrated measuring instrument. The rules that are evaluated include the default rule of ISO 14253-1, the recommendations of ILAC-G8, the 2 % probability of false accept (PFA) in ANSI/NCSL Z540.3, the 4:1 test uncertainty ratio (TUR), and the simple and stringent acceptance decision rules of ASME...

Scott M. Mimbs,
NASA Metrology and Calibration ProgramNASA’s Kennedy Space Center (KSC) undertook implementation of ANSI/NCSL Z540.3-2006 in October 2008. Early in the implementation, KSC identified that the largest cost driver of Z540.3 implementation is measurement uncertainty analyses for legacy calibration processes. NASA, like other organizations, has a significant inventory of measuring and test equipment (MTE) that have documented calibration procedures without documented ... Details

This Guide was prepared by NCSL International toward the goal of uniformity in the field of instrumentation and measurement. The content of this guide was originally assembled by an ad hoc working group operating under the direction of the NCSLI 174 Standards Writing Committee. The working group hopes that the modifications offered here will provide a tool useful to the measurement community, primarily in converting quality manuals from "Z540-1.1994 (R2002)" to "ANSI/ISO/IEC...

Beverly Garcia,
JM Test Systems, Inc.The primary focus on this paper is the value of NCSLI membership. It will identify who the members are and how they came to NCSLI. It will also describe the work place benefits received from their membership. It will prove how our individual values as industry professionals increase proportionately with our involvement in the guild as well as ways to become involved in the various NCSL International functions and committees.

The National Standard, ANSI/NCSL Z540.3-2006, Requirements for the Calibration of Measuring and Test Equipment, prescribes the requirements for a calibration system to control the accuracy of the measuring and test equipment used to ensure that products and services comply with prescribed requirements. Included are the requirements for calibration of the measuring and test equipment by a calibration-servicing component of that system. This component is commonly referred to as a... Details
